Abstract: ABSTRACT OF THE DISCLOSURE      A slide fastener stringer includes a stringer tape and a series of fastener elements sewn to the stringer tape on one of the opposite surfaces thereof along its one longitudinal edge by means of double locked stitches composed of a needle thread and a looper thread.  The needle thread includes a thermoplastic monofilament yarn, and the looper thread includes a spun or multifilament yarn.  The stitching has been done from the tape side of the slide fastener stringer.  Loops of the looper thread hardly project from the topmost surface of the needle thread loops so that a slider is not likely to wear it out.  Each of the needle thread has a constricted por-tion which serves to keep the looper thread loops from becoming loose.  After stitching of the fastener elements to the tape, the thermoplastic monofilamentary needle thread has been heat set to suitably shrink and then become dimensionally stable.          The invention provides a stringer enabling a very smooth threading of a slider.

Abstract: DEVICE CONTROL SYSTEM            Abstract of the Disclosure The disclosed control system employs an existing stored program PBX to regulate the operation of devices located at one of a plurality of sites in accordance with one or more modes of operation as offered by an algorithm stored in the PBX memory  Each site is equipped with a control circuit to regulate the operation of the devices located at the site.  These control circuits are activated by the presence of an audio frequency on the telephone line associated with each site.  To minimize the impact of this scheme on the traffic capacity of the PBX time division switching network, all activated control circuits are concurrently connected to a single time slot, which supplies the required audio frequency.

Abstract: PRODUCTION OF CHROMIC ACID USING TWO-COMPARTMENT AND THREE-COMPARTMENT CELLS                       ABSTRACT OF THE DISCLOSURE   Chromic acid is now produced in simplified processing that also reduces acid contaminants, while using the alkali metal chromate typically available at an early stage in chromic acid production from chrome ore. In the process, chromate is converted to dichromate in the anode compartment of either a two-compartment, or three-compartment, electrolytic cell. During electrolysis, metal ion contamination is reduced. Withdrawn anolyte from this first cell may then be concentrated. The dichromate feed, possibly concentrated, is then introduced to the center compartment of a three-compartment electrolytic cell and flows through a porous diaphragm to the anode compartment of the cell. The anolyte from this later electrolytic cell, rich in chromic acid, can be concentrated, cooled, and the chromic acid recovered. Liquid removed from chromic acid recovery can be recycled. Alkali product is produced in the cathode compartment of each cell.

Abstract: ABSTRACT                         A method and an apparatus for feeding longitudinally moving pieces of timber       into a timber processing machine      operates according to the prin-ciple that the contours in the longitudinal direction of the piece of timber       are first measured by measuring devices          which exert minimal pressure on the piece of timber, after which the piece of timber is advanced to at least one control device        which is arranged immed-iately adjacent to the processing machine and acts laterally upon the piece of timber with a considerably larger align-ment force.  Measurement signals from measuring devices are processed in a conventional manner in a computer     from which the order signals are sent to the control unit with a determined delay.  The control device operates both as an alignment device, by aligning the piece of timber to the necessary feed attitude calculated in the computer, and as a control device in the stricter sense of the term by controlling the piece of timber while it is being fed into the processing machine.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for providing cigar wrappers for a cigar wrapping machine.  The cigar wrappers are stored in a bobbin which is a continuous web of porous sheet material which is wound into a roll with the cigar wrappers positioned upon one surface of the roll and compressed between the adjacent surfaces of the respective layers or turns in the roll.  The web is drawn from the bobbin to a transfer zone in the wrapping machine along a continuous path.  The web is diverted from the path around a knife edge which forms the upstream edge of a gap between two plates. The web passes from the knife edge around a roller and then back through the gap. The cigar wrappers are peeled from the web by the sharp turn of the web around the knife edge and they pass over the narrow gap directly onto the web which is moving back through the gap from the roller.  This overcomes a serious difficulty which was encountered in removing the cigar wrappers from the web.

Abstract: CONTROLLABLE INSULATING EFFECTS BY SELECTIVE  INTERPOSITION OF INSULATING PARTICLES IN A CAVITY OF AN ENERGY TRANSMISSION PANEL ASSEMBLY                  Abstract A system for selectively interposing particulate insulating material in a cavity of a transmission or window panel assembly employs an upper aperture into the cavity through which the insulating material enters and is removed.          A flow diverting means adjacent the aperture diverts positive pressure air flowing toward the cavity into the ambient atmosphere, and the momentum of the insulating material causes it to continue through the aperture and fill the cavity.  Suction pressure air flow out of the aperture removes the insulating particles, and ambient pressure air flows into the lower portion of the cavity through vents to lift the insulating material upward out of the cavity.  The flow diverting means confines the suction air flow out of the cavity to the conduit or communicating means connected to the aperture.  A mode selection valve means operatively connects one of either a blower inlet or a blower outlet to the air flow conducting conduit to create positive pressure or suction pressure air flow to fill or empty the cavity.  A storage chamber for the insulating material is preferably located in close adjacency to the panel assembly in the space between a suspended ceiling and an upper structure or floor of a building.  Branch valves operatively communicate the air flow with each storage chamber.  A system control means operates the branch valve and the mode selection valve and the blower to create the desired air flow for changing the status, either empty or filled, of the cavities.  The system control means includes temperature sensors for sensing the interior and exterior temperatures adjacent the panel assembly or a group of associated panel assemblies, and the temperature information is utilized to determine the most favorable status of the cavity to reduce heat load loss or heat load gain to the structure.

Abstract: PROTECTION SYSTEM FOR IMMUNIZING AN INVERTER    SYSTEM AGAINST A-C LINE VOLTAGE DISTURBANCES     Abstract:       When a-c power line voltage is rectified by a phase-controlled SCR rectifier bridge to develop an adjustable d-c bus voltage which is then con-verted by an inverter back to a-c for driving a load, such as a motor, line voltage disturbances, resulting from momentary power outages or major power reductions, will have a deleterious effect on the operation of the inverter system.  Such disturbances will cause improper firing of the SCR's and the d-c bus voltage may increase con-siderably, disrupting the normal operation of the inverter system and possibly destroying the switching devices in the inverter.  Immunization against the effects of the line voltage disturbances is obtained by shutting down or disabling (37,65-92) the phase-controlled SCR SCR rectifier bridge (10) anytime such a disturbance occurs.  In this way, while the output voltage of the rectifier bridge is effectively interrupted during the ocrurrence of each. line voltage disturbance, the inverter (26) will continue to operate in near normal manner in response to the d-c voltage provided by the filter capacitor (19).  At the conclusion of each dis-turbance, the operation of the rectifier bridge (10) will be slowly restored to normal to avoid overshoot of the d-c bus voltage.
